In this paper

we introduce the tree ring chronological features in the mountain area of the wulumuqi river.In tree ring sampling and overall arrangement

besides obeying the basic principles of dentrochronology

we also use runoff of each tributary

change of runoff consitute with altitue

perpendicular climate condition and so on as reference basis.We sample 190 trees at 9 sites

develop 9 tree ring chronologies which contain 280 sequences.In the Region

which area is about 1000 km 2

there are 9 sampling site

it is singls in our country.In these tree ring chronologies

the number of maxmum sequence is 47

the minmum is 17

the longest is 452 years and the shortest is 195 years. The mean sensitivity

standard deviation and cross correlation of these tree ring chronlogy are greater than that of the tree ring chronology sampled in Hami

Changji

Aletai

Yili

middle and down reaches of Talimu river and so on areas

this show that the quality of tree ring chronologies in the mountain of the Wulumuqi river is very good.From these tree ring chronology

it is possible to reconstruct the reliable and long seuence of climate in past several hundred years.
